Ok this is kinda tricky for me.. my question is.. i have a new update address book that i need to push to my employees bb. problem is would their personal contact would be erase after the address book push from BES?
i only want to replace the same contact with updated info. but also want to keep their personal contact, like family and friends etc...
any can one help?

Are you a Domino or a Exchange shop? Also I'm assuming you are using BES 4.0? We use Domino and when I've had to do changes for users, I just get access to their mail file directly and copy and paste the entries I need to change.
